INTRODUCTION
The Palos Verdes Peninsula Land Conservancy (PVPLC) received grant funding through the California Department of Fish and Game’s Local Assistance Grant program to produce a fine- scale, spatially and floristically accurate vegetation map of the Palos Verdes Nature Preserve (PVNP). The PVNP is part of the draft Rancho Palos Verdes Natural Community Conservation Plan (RPV-NCCP) area, and encompasses approximately 1200 acres of protected open space. The PVNP is located in the City of Rancho Palos Verdes, in southern Los Angeles County. The project area represents several biologically rare habitat types, including coastal sage and cactus scrub. In addition, the PVNP hosts several rare and endangered plant and animal species, which are classified as covered species in the RPV-NCCP. Vegetation resources were assessed through field surveys, resulting in the classification analysis of 26 vegetation alliances, 38 vegetation associations or semi-natural stands, and mapping of 583 vegetation map polygons.
BACKGROUND AND OBJECTIVES
The primary objective of this project was to create an accurate baseline vegetation map for the RPV-NCCP. When the NCCP was initially prepared in the late 1990’s, floristic information of the area was based on existing surveys, many of which had been prepared for development projects. There was inconsistency in the terminology, level of detail, and scope between the various sources. The initial vegetation maps used in the draft RPV-NCCP were merged from several sources of data, which was adequate at the time. However, they did not provide the level of information that would be most valuable for long-term preserve management. This project has allowed for a detailed, on-the-ground vegetation survey of the PVNP using the California Native Plant Society’s Vegetation Rapid Assessment protocol and the latest quantitative classification methods. The resulting vegetation classification follows the Manual of California Vegetation (Sawyer et al. 2009), which is the current standard for interpreting state- wide vegetation patterns and for initiating local and regional ecological assessments. The combination of survey data and the classification of the local vegetation were used to produce a detailed, accurate vegetation map of the PVNP.
To complete the objectives of the project, the PVPLC contracted with the California Native Plant Society (CNPS) to train and assist staff with the PVPN vegetation mapping. CNPS was contracted to perform the following tasks: 1) Provide strategy, protocols, and training for vegetation sampling; 2) Assist with field surveys; 3) Provide training for vegetation mapping and attribution; and, 4) Assist in final reporting and review. CNPS is a state-wide non-profit organization whose mission is to conserve California native plants and their natural habitats, and increase understanding, appreciation, and horticultural use of native plants.

METHODS
The CNPS vegetation rapid assessment protocol was used to survey vegetation types in the PVNP, a nine reserve area in Rancho Palos Verdes, CA (Figure 1). The rapid assessment protocol is a reconnaissance-level method of vegetation and habitat sampling. The quantitative vegetation and habitat data recorded in the field was used to develop a vegetation classification and to provide attributes for mapping using a digital geodatabase and GIS mapping software.

FIELD METHODS Training in CNPS field sampling protocols was conducted during February 24 -27, 2009, where CNPS biologists trained PVPLC staff and interns on the methodology of Vegetation Rapid Assessment and Relevé sampling methods (CNPS 2007, 2009). The protocols outline vegetation stands as the basic mapping unit. A stand is defined as an area of vegetation that has both compositional and structural integrity and represents a homogenous vegetation type that is repeated across the landscape. Stands can be selected prior to a site visit using aerial photos or other reconnaissance methods, or may be selected on site. Once a stand is selected, a field form is completed (Appendix A) that records both vegetation and environmental data. Plant identification was accomplished using forensic guides for the region as references (Hickman 1993, Sawyer and Keeler-Wolf 1995).
As a result of the field training, a series of mapping rules were established for the project (Table 1). Field vegetation sampling continued through April 2009 by PVPLC staff and interns. During April 7 – 10 and April 28 – May 1, CNPS staff assisted in two additional field survey efforts. Between the two field survey efforts in April, CNPS reviewed the data collected up to that point, and provided additional sampling suggestions, a preliminary key to vegetation types in the PVNP and a list of alliance-level vegetation groups found to date.
CLASSIFICATION ANALYSIS CNPS staff used multivariate analysis and existing classifications to classify the PVNP field data collected in the spring of 2009. Data was run through a cluster analysis using the PCORD software package to identify patterns and groups in the data. Cluster Analysis with a hierarchical agglomerative technique was employed using Sorenson distance and flexible beta linkage method at -0.25. The cluster analysis was based on species abundance (cover) values converted to 7 different classes as defined in the sampling protocols. The data also were compared to existing classifications in southern California (such as Keeler-Wolf and Evens 2006). An alliance and association level classification resulted, following state and federal standards (see Sawyer and Keeler-Wolf 1995 and NatureServe 2009).

VEGETATION MAPPING Post field-data collection, all surveys were entered into a standardized database. Geographical information system (GIS) mapping software was used to digitize the vegetation stands into polygons with individual attributes associated with each polygon stand. To validate the vegetation map, reconnaissance-level field verification was conducted by PVPLC field staff, as directed by CNPS staff. A thorough quality assessment and quality check (QA/QC) was performed in both GIS and the field. Staff visited over 50% of the polygons mapped through both the vegetation rapid assessments and the post mapping field verification to ensure a high degree of floristic and spatial accuracy in the map. The information was stored in an ArcGIS geodatabase. Associated survey information was also stored electronically in tables. Digital photographs of field surveys were archived electronically into folders labeled by survey date.

RESULTS
In the 152 vegetation surveys of the PVNP, 150 vascular plant taxa were identified. General names were used for nonvascular plants or vascular plants not identified to the species level (e.g., Moss, Lichen, Graminoid). Appendix B provides a complete list of scientific and family names for all taxa identified. Appendix C depicts snapshot examples of all the vegetation association or stand types mapped in the PVNP. Appendix D identifies key environmental factors associated with each vegetation rapid assessment plot. Appendix E outlines every rapid assessment plot by vegetation alliance, associate, and property. Appendix F is the vegetation mapping classification created specifically for the PVNP by CNPS. Appendix G provides a summary of species composition and abundance values for vegetation associations/stands identified during the survey of the PVNP. Appendix H is a field key to the floristically defined vegetation types defined and mapped in the region.
The floristic classification for the PVNP includes 28 vegetation alliances (Table 2). Some of the more common native vegetation types found in the PVNP include Baccharis pilularis (coyotebrush), Artemisia californica (California sagebrush), Salvia leucophylla (purple sage), and Rhus integrifolia (lemonadeberry), and Salix lasiolepis (arroyo willow) alliances. Uncommon vegetation types in the PVNP include: the special stand Crossosoma californicum (crossosoma), Opuntia littoralis and Cylindropuntia prolifera (cactus), Nassella lepida (foothill needlegrass), Leymus condensatus (giant wildrye), Hazardia squarrosa (sawtooth goldenbush) alliances, and all associations including Eriogonum cinereum (ashy buckwheat).
Non-native vegetation was commonly identified throughout the PVNP, repeating across the landscape as large, dominant stands, as well as, individual plants within native stands. In general, most herbaceous stands were observed and documented to have an abundance of non-native species such as Brassica nigra, Bromus spp., and Foeniculum vulgare. Some native species including forbs may occur in these stands, and they may fluctuate seasonally.
Vegetation stands adjacent to urban areas tended to be disturbed by non-native species and other human-level disturbance factors unless the area was sloped and generally inaccessible. In these cases, native vegetation on the slopes was dense and generally undisturbed by non-native species and other human impacts. Another common trend found was that along trails and roads, non-native species were most dense. Rare and covered species were generally found in areas less accessible with limited trails and roads.

DISCUSSION
The results of this project are a detailed, accurate map of the vegetation in the PVNP. This information can now be used to answer questions ranging from species-specific management to targeting the most likely places to reduce fuel loads. We can now find precise location information for specific habitats of NCCP-covered species, identify areas for conservation within sensitive natural communities and habitats with invasive species, restore habitat value based on various attributes, and create linkages to wildlife habitats through restoration.
As an example, in the short time these data were being finalized, the PVPLC was able use the vegetation map and sampling data to develop a fire recovery plan for a wildfire that occurred on August 27, 2009 in the Portuguese Bend Reserve. The wildfire burned approximately 165 acres within the PVNP and the mapped vegetation stands were used as a pre-fire baseline (Figure 2) for post-fire recovery and restoration.
When considering management issues across the entire PVPNP, it is important to view the land in its entirety and how it functions within the surrounding urban matrix. Approximately 41% of vegetation polygons are adjacent to urban areas (Figure 3). Management activities should be approached with the goal of sustaining native habitat and populations in the context of an urban environment. Invasive species and unauthorized trails appear to the largest threat to preserving intact native vegetation stands in the PVNP.

Trails occur throughout most of the PVNP, and while multi-use trails are a permitted use, unauthorized social trails result in habitat degradation, species disturbance, and conduits for invasive species movement. It is recommended that enforcement of authorized trail use continue, with an increased focus on unauthorized trail closure, restoration of these disturbed areas and public education through accurate trail signage and interpretive panels.
Invasive species are a ubiquitous problem in wildlands, and are present throughout much of the PVNP. Invasive species pose a substantial threat to the integrity of native vegetation communities in the PVNP. Of particular concern are highly invasive species such as Euphorbia terracina (Geraldton carnation spurge) located in Portuguese Bend Reserve and San Ramon, Ricinus communis (castor bean) located in Agua Amarga and Abalone Cove, and Acacia cyclops (acacia) found through the PVNP. The vegetation surveys and map allow for PVNP staff to prioritize and target areas for restoration.
In addition to the highly invasive species listed, ornamental species located along the many PVNP boundaries are a potential future threat, as their ability to become invasive is unknown. Aggressive non-native plant control is a highly recommended priority for the long-term preservation of established and future recruitment of native vegetation stands in the PVNP. Management priorities should include highly invasive species as listed by the California Invasive Plant Council (Cal-IPC) and the US Department of Agriculture, as well as those already defined by the PVPLC’s Targeted Exotic Plant Removal Program for Plants (TERPP).
While the primary purpose of this project was to map and quantify vegetation types in the PVNP, the outcome is the ability to assess and document habitat quality for covered species under the RPV-NCCP. Using the vegetation map, the PVPLC can approach habitat restoration, targeted invasive removal and trail improvement projects systematically, focusing on areas of concern. Projects could include linking island-like stands of native vegetation through habitat restoration or enhancement and increasing the vegetation stand size know nesting sites of covered bird species. As an example, and again referring to the burn area of Portuguese Bend Reserve, recovery efforts have been prioritized by similar principals. Surveyed locations of covered bird populations, California cactus wren (Campylorhynchus brunneicapillus) and California gnatchatcher (Polioptila californica), were overlaid, using GIS, onto the pre-fire vegetation map. Proposed habitat restoration zones were then delineated based on the bird population locations in relation to vegetation stands. Moreover, the PVPLC will be able to utilize the vegetation map as a baseline for the three-year, 15-acre habitat restoration plan as required by the RPV-NCCP.

APPENDIX G
SPECIES COMPOSITION/ABUNDANCE TABLES FOR THE VEGETATION TYPES
The PVNP association and stand types are summarized within five species composition/abundance tables (1-5). The table below provides codes that are used to identify each vegetation type, as well as the species composition/abundance table for which it can be found. Each species composition/abundance table includes the number of stands sampled under the code for the vegetation type. Each table also includes abundance and frequency values for those plants that occur at 33% or greater constancy across all stands sampled for each type. The first number represents the average percent absolute cover of the plant in the stands sampled, and the number in parentheses is the percent frequency (or constancy) for the plant occurring in these samples.

APPENDIX H
FIELD KEY TO THE FLORISTICALLY DEFINED VEGETATION TYPES IN PVNP WITH MAPPING CLASSIFICATION CODES AND NAMES
Class A. Vegetation with an overstory of trees (at least 5 m tall). Absolute tree canopy cover is generally >10% but occasionally may be < 10% over a denser understory of shrub and/or herbaceous species.
